I am in the process of setting up my first nano tank for my office. I only have experience with larger tanks, so I need some help. I have already ordered a JBJ 6 gallon system. That is simply all that I have room for. I already have the sand and the corals I am going to use are already growing in my main display at the house. Xenia elongota, orange cap, brown cap, star polyps, and several varieties of zos. I however, have no idea where to get good rock. I am considering the nano pack from either fosters and smith or marinedepot live. Has anyone ever ordered from these two? Quality, size, etc.. If any of you have any "better" alternate suppliers please let me know. Thanks in advance!
